Magnum RT steps are the newest and unique truck sidestep bars. The RT sidestep bar features a sharp drop-down step design featuring a wide step area for easy entry and exit of your truck or jeep. The sidestep pads have a non-slip tread for added safety and are slotted to allow drainage so that snow or mud does not collect as on a truck running board. The magnum RT sidesteps form fit to your truck or jeep lower rocker protecting from rocks while off-roading and road grime on the street. Designed and engineered in the U.S.A., magnum RT side steps are built to last. That's why magnum offers a 1-year warranty on the finish and a limited lifetime on the structure.
